Modeling and Simulation of a Cooling System Using Multiport Approach 2000-01-0292

In the analysis of a cooling network, Computational Fluid Dynamics methods show an unquestionable usefulness. Nevertheless, this approach is largely limited for simulating the behavior of multidisciplinary components connected in a system. The lumped parameter approach suits these systems simulation. This awareness has led to the development of methods for structuring these kinds of problems.

Applying the multiport method, the Thermal, Thermal-hydraulic and Cooling system libraries were created. These libraries comprise a set of basic and specific components from which it is easy to model large thermal-hydraulic and engine cooling networks. These basic and specific elements facilitate the study of phenomena whose knowledge is indispensable for the analysis of a whole system. An application of these libraries to a RENAULT car is presented.
